FIELD OF THE INVENTION

The present invention relates to cosmetic compositions comprisingsilicone elastomers comprising entrapped or encapsulated pigmentswherein said pigments are entrapped or encapsulated by the siliconepolymer network. Preferably these compositions also exhibit thedesirable property of forming films that are transfer resistant. In aspecifically preferred embodiment, the invention relates to atransfer-resistant personal care and/or make-up composition for the skinof both the face and the human body, for the mucous membranes such asthe lips and the inside of the lower eyelids, or alternatively for thesuperficial body growths such as the eyelashes, the eyebrows, the nailsand the hair. This composition may be provided in particular in the formof a product cast as a stick or in a dish such as lipsticks or lipbalms, cast foundations, concealers, eyeshadows or blushers, in the formof a paste or a cream which is fluid to a greater or lesser degree suchas fluid foundations or lipsticks, eyeliners, compositions forprotecting against sunlight or for coloring the skin.

BACKGROUND OF THE INVENTION

Make-up or care products for the skin or the lips of human beings suchas foundations or lipsticks generally contain lipophilic or fatty phasessuch as waxes and oils, pigments and/or fillers and, optionally,additives such as cosmetic or dermatological active agents. They mayalso contain so-called “pasty” products, of soft consistency, which makeit possible to obtain pastes, colored or otherwise, to be applied with abrush. These compositions, when they are applied to the skin or thelips, have the disadvantage of transferring, that is to say of becomingdeposited at least in part, leaving marks, onto certain supports withwhich they may be brought into contact, and in particular a glass, acup, a cigarette, clothing or the skin. This results in poor persistenceof the applied film, requiring regular renewed application of thefoundation or lipstick composition. Moreover, the appearance of theseunacceptable marks especially on blouse collars can prevent some womenfrom using this type of make-up.

For several years, cosmeticians have been interested in lipstickcompositions and, more recently, in foundation compositions which are“transfer-free”. Thus, “transfer-free” lipstick compositions containinga siloxy silicate resin (with a three-dimensional network), a volatilesilicone oil with a cyclic silicone chain and pulverulent fillers havebeen described. Likewise, “transfer-free” lipstick, eyeliner andfoundation compositions containing one or more volatile siliconescombined with one or more hydrocarbon waxes have been developed.

Although exhibiting enhanced “transfer-free” properties, thesecompositions have the disadvantage of leaving on the lips, afterevaporation of the silicone oils, a film which becomes uncomfortableover time (feeling of dryness and tightness), a significant drawback tothe retail purchaser of cosmetics. To enhance the comfort of this typeof composition, nonvolatile silicone or nonsilicone oils may be added,but this particular solution to the problem results in a loss of some ofthe “transfer-free” properties.

More recently, water-in-oil emulsion-type mascara compositions have beendescribed that exhibit long retention, resistance to water and which donot leave marks. These compositions contain, inter alia, awater-insoluble polymer generally called a latex, combined with asurfactant of the alkyl or alkoxy dimethicone copolyol type, hydrocarbonoils, pigments and fillers as well as waxes.

The compositions based on silicone oils and silicone resins as well asthose based on latex provide matte colored films. However, manypurchasers of cosmetic products are looking for glossy productsespecially for lip coloring. Furthermore, the transfer-free propertiesof the films deposited are not perfect. In particular, substantialpressure or rubbing leads to a decrease in the color of the deposit andto redeposition on the support brought into contact with these films.

Compositions containing a styrene-ethylene-propylene block polymercombined with waxes, light or volatile oils and pigments exhibitso-called “transfer-free” properties. However, these compositions havethe disadvantage of not being comfortable to any great extent, havingpoor cosmetic properties, and being difficult to formulate. Moreover,the “transfer-free” properties of these compositions are only average.

A variety of silicone compositions may be utilized to impart desirableproperties, e.g. transfer resistance, to cosmetic compositions and/orformulations, e.g. MQ resins, silicone gums, MQ esters and alkylsilicones. While cosmetics utilizing MQ resins possess the property oftransfer resistance, formulations containing most MQ resins exhibit anunpleasant pulling sensation and additionally do not stabilize theformulation. Alkyl silicones offer transfer resistance, enhanced sensoryproperties and a somewhat reduced syneresis. These advantages come atthe price of high levels of the alkyl silicone in the cosmeticcomposition, e.g. 13-30 wt. %, levels that significantly reduceformulation flexibility.

The need, therefore, still exists for a composition that does notexhibit the above disadvantages, and having in particular“transfer-free” properties even during substantial or intensive pressureor rubbing, an appearance which is glossy to a greater or lesser degree,in line with the wishes of the consumer, which does not cause the skinor the lips to which it is applied to dry out over time.

SUMMARY OF THE INVENTION

The present invention provides for a pigmented cosmetic compositioncomprising:

-   -   (a) a silicone gel comprising an entrapped, occluded or        encapsulated pigment; and a dispersant medium. More particularly        the present invention provides for a colored cosmetic        composition wherein the silicone gel comprising entrapped,        occluded or encapsulated pigment is selected from the group of        gels consisting of:        -   (i) a gel formed from a silicone and a hydrosilylation            compatible solvent wherein said silicone is prepared by the            hydrosilylation of a linear alkenyl polyorganosiloxane and a            hydride resin;        -   (ii) a gel formed as a reaction product of an epoxy            functional hydrido-siloxane said reaction product being            formed in an epoxy-gel formation compatible solvent;        -   (iii) a gel formed from a silicone and a hydrosilylation            compatible solvent wherein said silicone is prepared by the            hydrosilylation of a linear hydrogen polyorganosiloxane and            an alkenyl resin;        -   (iv) a gel formed from a silicone and a hydrosilylation            compatible solvent wherein said silicone is prepared by the            hydrosilylation of a linear hydrogen polyorganosiloxane and            a linear alkenyl polyorganosiloxane;        -   (v) a gel formed from a silicone and hydrosilylation            compatible solvent wherein said silicone is prepared by the            hydrosilylation of a hydrogen polyorganosiloxane resin and            an alkenyl polyorganosiloxane resin;        -   (vi) a gel formed from a silicone and a hydrosilylation            compatible solvent wherein said silicone is prepared by the            hydrosilylation of a linear hydrogen organopoly-siloxane            having two or more hydride functionalities per molecule and            an α, ω reactive organic molecule possessing two or more            reactive functionalities per molecule; and        -   (vii) a gel formed as a reaction product of a vinyl            functional hydrido-siloxane in a hydrosilylation compatible            solvent.

This present invention provides for a new method for preparation ofswollen cross-linked silicone network compositions by incorporating thepigments prior to the cross-linking reaction, thus entrapping, occludingor encapsulating the pigments within the silicone network. Currently,when pigments are used along with swollen cross-linked siliconematerials, they are physically mixed resulting in independent gel andpigment phases. This can, especially in the case of solid inorganicpigments, cause reagglomeration resulting in color shift andinhomogeneities.

DETAILED DESCRIPTION OF THE INVENTION

Applicants have discovered that improved cosmetic compositions areobtained from pigmented and/or colored cosmetic compositions that mayalso be rendered transfer resistant by the incorporation of a siliconegel comprising an entrapped, occluded or encapsulated pigment or coloredmaterial into the formulation of the colored cosmetic composition. Asused herein, the terms entrapped, occluded or encapsulated are used moreor less interchangeably and have a functional definition that when a gelcontaining encapsulated, occluded or entrapped pigment is contacted witha suitable solvent (e.g. paraffinic, aromatic, alcoholic, or mixturesthereof as well as other solvents such as water or acetone) andvigorously shaken or stirred allowing the mixture to come to rest shouldresult in only two apparent phases, the gel phase and a supernatantsolvent phase. In the event that three apparent phases result from sucha qualitative experiment, a pigment phase, a gel phase and a supernatantsolvent, the pigment is deemed to be encapsulated or entrapped if lessthan 10% by weight of the original pigment is recovered from such aprocess based on the amount of pigment originally introduced into thegel.

As used herein transfer resistance is resistance to the transfer ofcolored material in a color cosmetic from a first substrate to which thecolored cosmetic is applied to a second substrate under the applicationof a transferring force such as pressure.

As used herein the phrase “silicone gel” refers to any siliconecontaining material that increases its volume upon contact with a lowmolecular weight solvent that may or may not be volatile wherein thesolvent diffuses into the silicone containing material.

As used herein the terms polyorganosiloxane and organopolysiloxane areinterchangeable one with the other.

As used herein the term “colored material” refers to physiologicallyacceptable dyes, pigments or other coloring material known to thecosmetic arts. The term “physiologically acceptable” is an accepted termof art and refers to topical application on humans.

As used herein the phrase “silicone containing material” refers tooligomers, polymers, copolymers, terpolymers and higher order polymersof silicon containing repeat units, copolymers and higher orderinterpolymers containing silicon repeat units with organic polymers. Asused herein “organic polymers” means organic polymers wherein the repeatunits do not contain silicon atoms in the polymeric backbone or chain.Thus for example, some silicones gels useful in the compositions of thepresent invention are polymeric, cross-linked, networks oforganopolysiloxanes or block copolymers of organopolysiloxanes andorganic polymers. The cross-linking of either type of network may beachieved by cross-linking units based on siloxanes comprising hydrido-,vinyl-, epoxy-, acrylate-, acetoxy-, or alkoxy-groups and the like andmixtures thereof and when such materials contain organic polymers as acomponent, organic compounds or oligomers capable of joining polymericunits together, e.g. terminal polyolefins, terminal polyolefinic ethers,acrylates, epoxides and the like and blends thereof. Silicone gelsuseful in the compositions of the present invention are exemplified inthe following U.S. Pat. Nos. 4,987,169; 4,980,167; 5,760,116; 5,811,487and 5,138,009 hereby and herewith specifically incorporated byreference.

As used herein the phrase “low molecular weight volatile solvent” refersto any solvent compatible with topical application to human beingswithout adverse effect thereto that has a vapor pressure between thetemperatures of 0° C. and 100° C. ranging from about 1 mm Hg to 760 mmHg.

The lipsticks were tested for transfer resistance using the followingmethod. Seventy mg of the tested lipsticks was uniformly applied to a2″×3″ pork intestine slide and air dried for 4 hours. A white T-shirtwas placed on the surface of the lipstick coated pork intestine slideand pressed with a 500 g weight by rotating the weight in a 360 degreeor one circular motion. The amount of lipstick transferring to theT-shirt was measured by a ColorEye 7000 (available from Gretag-Macbeth,617 Little Britain Rd., New Windsor, N.Y. 12553). The “a” value on theHunter L, a, b color scale was used as an indicator of rub-out and thustransfer resistance. The “L” value is the measurement on a black andwhite scale (0-100) where the higher the number the whiter the color,with zero representing black, and 100 representing white. The “a” valuerepresents a red-green color scale where a positive number representsredness and a negative number represents greenness. The “b” valuerepresents a blue-yellow color scale where a positive number representsyellowness and a negative number represents blueness. In these examples,the “a” values were used as an indicator of rub-out because the onlycolored material used was D&C red #7 Ca Lake. Since only a red coloringmaterial was used, the “L” and “b” number does not reflect any transferand was not used for any experimental evaluation. The average “L,” “a,”“b” values (average of 5 samples per formulations) are shown in TableII.

Transfer resistance as it applies to the silicone gel comprisingformulations of the present invention is more quantitatively defined bya comparison to a control formulation that does not contain a siliconegel material where both the control and candidate formulation(s) havethe same weight percent dye or pigment in the cosmetic formulation. Thusa percent reduction in the intensity of color transferred can becomputed using the following formula (based on “a” values of the L, a, bcolor scale):Percent transfer reduction=100(a_(control)−a_(tested formulation)/a_(control))where a_(control) is the “a” value on L,a,b scale of controlformulation,

a_(tested formulation) is the a value on L,a,b scale of color cosmeticcontaining silicone gel. The same formula can be used for the yellow(positve b)-blue (negative b) color couple, “b” values, and green color(negative values of “a”) making the proper algebraic adjustments whenthe scaled numbers are negative numbers.

Lipstick formulations containing silicone gels show the lower numbersfor the “a” value indicating a lower level of color transferred to theT-shirt during the rub-out testing, i.e. a higher transfer resistance,i.e. a greater percent transfer reduction. Qualitative evaluations werealso made of the transfer resistance of the lipstick formulations.Samples 1 and 2 gave slightly better transfer resistance than sample 3.By comparison to the control, all the silicone gel containing lipstickformulations provided excellent rub-out protection. These results areconsistent with the quantitative values for “a.” After three days atroom temperature, syneresis was noticeable in the control formulationbut in contrast the silicone gel containing samples did not exhibit anysyneresis.

The lipsticks were tested for transfer resistance using the methodpreviously described. Seventy mg of the tested lipsticks was uniformlyapplied to the 2″×3″ pork intestine slides and aired dried for 4 hours.A white T-shirt was placed on the surface of the lipstick coated porkintestine slide and pressed with 500 g weight by rotating the weight ina 360 degree or one circular motion. The amount of lipstick transferringto the t-shirt was measured by a ColorEye 7000 (available fromGretag-Macbeth, 617 Little Britain Rd., New Windsor, N.Y. 12553.) The“a” value on the Hunter L, a, b color scale was used as an indicator ofrub-out and thus transfer resistance. The “L” value is the measurementon a black and white scale (0-100) where the higher the number thewhiter the color, with 0 representing black and 100 representing white.The a value represents red and green color where the positive numberreflects the red color and the negative number represents green color.In this study the lower a value represents less transfer and is moredesirable. The b value represents blue and yellow and the positivenumber represent yellow and negative number represents blue. In thisstudy the a value was used as an indicator of rub out magnitude due tothe presence of D&C red # 7 Ca lake in the formulations. Since only redcoloring was used the L and b number does not reflect transfer in thisparticular instance and was not used for evaluating the formulations.The average Lab value results were shown in the table below. TABLE 4Transfer Resistance Values for Panel 2 Lipsticks Percent TransferSamples L a b Reduction 5 83.86 13.12 −9.62 — (Control) 6 84.08 10.86−9.89 17% 7 81.33 12.19 −9.54  7% 8 82.23 10.41 −10.32 20%

In this examples the primary indicator of transfer resistance is the “a”value. Lipsticks containing silicone gel show lower numbers of a value,which demonstrates the lower color transfer of the lipsticks from thetested slide to T-shirt during the rub-out testing. The ranking oftransfer resistance from high to low is as follows: Sample 8>Sample6>Sample 7.

Although these tests measured lipstick formulations other color cosmeticsuch as lipsticks, foundations, face powders, eye liners, eye shadows,blushes, makeup, and mascaras although not limited thereto may besimilarly measured by a red-green or blue-yellow color scale as hereindefined. As measured by the previously defined test, the transferresistant color cosmetic formulations of the present invention exhibit apercent transfer reduction value of 7% or greater, preferably 17% orgreater, more preferably 20% or greater, and most preferably 34% orgreater.

Cosmetic formularies list many different color cosmetic formulationswhere waxes or other solid materials and cosmetic fluids also includingsilicone oils may be replaced by the silicone gels of the presentinvention gels I through VII), thus imparting transfer resistance to theformulation, e.g.
